6l90E 2wd 36 spline to 4X4 NP205 27 spline drive coupling idea???

All The th400 and late 85+ GM sm465 205’s are all 32 spline big bearing inputs if that helps. The 85+ 205’s are the best, strongest, and most sought after.

I can’t see why this wouldn’t work as long as you got the shafts coupled together. It’s really no different than the spacer that goes on the back of 700r4 to mount a th350 Np205 to it. (there’s a bit more to that conversion but the end result is the same)
